Ok, I will call it so-called Earth's rotation if it makes you happy LOL. Clearly, you need to be pedantic because you have nothing but your cartoon ball Earth and its accompanying explanations.
None of it is a problem for FE, sorry - here you have an explanation, since you live for explanations:
Are you seriously offering that video up as a credible explanation for anything at all?
From start to finish he makes absolutely zero sense. Let's pick out just a few things that he says that are demonstrably, observably wrong:
- as with his other video that you cited, he draws mag flux lines making a figure of eight pattern viewed from the side, with the dip angle increasing at the equator - that is the exact opposite of the observed dip angle. It is simply false - the dip angle is at its lowest in the region around the equator, and at its highest closest to the two poles.
- he draws curved flux lines radiating out from his southern 'rim' in a consistent pattern, which then reverse at the equator. That bears no resemblance whatsoever to the observed mag declinations at different places around the world. Again - you can check this yourself using published mag dec figures, which you can back up using things like published aeronautical and maritime charts (where they have to be correct in the interests of safety and are routinely checked and verified by users) as well as your own observations using a compass.
- he claims that sigma octantis moves when observed through time lapse. It doesn't.
These things aren't matters of opinion - they are demonstrably wrong. He is wrong. You are wrong. If you were really interested in the subject, you could prove this for yourself very easily.
